Solve for x first

X+y=54

X-y=10

Add

2x=64

Divide

X=64/2

X= 32

So now get one equation and substitute x to solve for y

32+y=54

Y=54-32

Y= 22

So your two numbers is 32 and 22.

To check substitute

32+22=54

32-22=10

They check

loris [4]

10 more than (+ 10) a number (x) is greater than (>) 50

x + 10 > 50

To solve, subtract 10 from both sides.

x > 40

Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

PEMDAS

Parentheses
Exponents
Multiply
Divide
Add
Subtract

BODMAS

Brackets
Order
Divide
Add
Subtract

First, do parentheses.

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

Do multiply and divide.

6*9=54

54/3=18

Then, rewrite the problem down.

$\Longrightarrow: \sf{3+18-7}$

Add.

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

Therefore, the correct answer is "C. 14".

I hope this helps, let me know if you have any questions.
